The fast and easy solution
The company entered into discussions with Experian Data Quality, and quickly discovered a solution to the bad email problem: a batch cleansing of suspected invalid emails. Experian Data Quality offers an email batch cleansing service, which checks email addresses for several different types of errors. At any point in the process, if an email fails a certain check, it will be deemed “invalid.”
First, the email syntax is examined. Next, the email address is tested to ensure that the user name format is compliant with the particular email domain. Then the email address is compared to an internal database of known bad email addresses. Finally, a request is sent to the email service provider to determine whether the user actually exists (only certain domains allow this last check).
After a quick data test on a sample of bad email addresses, the company purchased a batch cleansing of the email database. According to the data management manager, the project was fairly low-effort from his perspective. “The cleansing process was easy for us – we just sent the file off to Experian Data Quality. Our biggest effort was working with our IT group to create a new process to ‘unflag’ certain bounced emails.”
The retailer soon received the processed file back from Experian Data Quality. A significant portion of the email addresses were designated as valid, so the team updated their marketing database with the new data.
Measuring the impact
The company began testing the recovered email addresses through email marketing communications. Two weeks later , the data management manager was more than satisfied with the results. “We reached ROI in far less than two weeks. The data test had given us an estimate of what to expect from the cleansing – but the results far exceeded expectations. This was 100% worth our time and money.”
Armed with greater confidence in the quality of its email data, the team can ensure that as many subscribers as possible are able to receive its weekly marketing communications, maximizing return from these campaigns.
Results
The retailer was able to realize a return on the investment in the email batch cleansing service within two weeks. A sizable portion of the suspected bad emails was recovered, tested by the marketing team , and then added back into the retailer’s marketing database, meaning that the company can now contact as many subscribers as possible through email .
